Atlona (Dual Link) DVI to Mini DisplayPort Converter for Apple 27-inch LED and 27-inch iMac. Model: AT-DP400

The Atlona AT-DP400 is a DVI to Mini DisplayPort converter designed to convert signal from any Mac or PC computer with a dual link DVI output to a digital signal over a Mini DisplayPort connector. The AT-DP400 is specifically designed to work with iMac 27-inch and 27-inch LED which can support resolutions up to 2560x1600. Users can use the connected monitor as their main display or extend their desktop using it as an additional screen. The Atlona DVI to Mini-Display Port Converter is compatible with all Apple and PC Computers which have a DVI or Mini-DVI connections. The DP400 features an attached DVI cable and uses USB as power source, leaving no need for an external power supply.

Important Notes:

Note1: For PS3 or Xbox users, you can use the DP400 converter without additional devices at resolutions up to 720p. Make sure to set your source to 720p prior connecting it to the DP400. Even through DP400 is able to pass-through very high resolutions, the Xbox or PS3 will only be able to view 720p because iMac 27-inch doesn't accept 1080i or 1080p, for this application we recommend the AT-HD620 (HDMI to Mini DisplayPort Scaler)

Note2: The DP400 requires Dual Link video card which support 2560x1440 in order to output 2560x1440 to a display. Please make sure you card is Dual Link.

Note3: The AT-DP400 will not support 2011 iMac 27-inch with Thunderbolt connection, Atlona is working on a new product which will.
